With inspirational input from some Users on other platforms I created an iPhone "Shortcut App" instruction sheet for two automations.
1rst a "WiFi plus App open" shortcut-procedure and for those who still have Problems with the connection 2nd a "Bluetooth-Wifi workaround" which switches a probably still connected home WiWi shortly off and on again to force a new connection with the Bike.
After programming that throwing your unlocked iPhone in the cubby is the last you have to do with that device. No WiFi acceptance needed and Maps start and -more important- restarts on its own. In case you need to start a planned route it's obvious that you need to choose and start it manually.
Screenshots are in German only but as the instructions are bilingual you should be able to find the right buttons. If not, hand the phone over to your grandkids.:-) Have fun! It works!
